Just putting this post out there to let people know that flyspecking is as much a part of stamp collecting as any other part....My interpretation of flyspecking is as follows summed up in 2 sentences.
FLYSPECKING
1-To see what is there that should not be.
2-To see what is not there that should be.
I took a few strips of 4, Scott 96 "Prince and Princess of Wales" Quebec Tercentenary Issues that were laying in the bottom of one of my boxes...None were taken from filled collection.
These examples below are NOT earth shattering,...99% are just oddities/freaks/errors etc., but you can find interesting possible constant varieties...An example is my find of Scott 56,57 and 58 Newfoundland "Dog Scratch" constant variety...From 123-132 years ago...So there are good finds out there.
RE-ENTRYHere is the r-entry associated with the one on Ralphs re-entry.com web page..You can see the re-entry with no problem as shown by the picture below.


ODDITY ONEA doted line running across the stamp between line 3 and 4 at the top of the Scott 96...Good oddity.
ODDITY TWOInside frame line on Princess side has dots that look like a possible re-entry "" probably not""..The YELLOW arrows show the oddity and the RED arrows show a normal stamp.
ODDITY THREEThe numeral box on all stamps have 4 bars..3 are equal length and one shown by YELLOW arrows is always shorter.

ODDITY FOURDots outside UL frame of stamp

ODDITY FIVEThere are always 4 scrolls at the top of the stamp...Princess side has a outer border shown in RED and the Prince side the left border shown in YELLOW does not have a border but the right scroll always has a border as shown by the RED arrow.
ODDITY SIXNow this is a really good oddity...The stamp on the left between line 6 and 7 has a smaller space that the one on the right which is normal.

ODDITY SEVENHere is an example of a Ductor Blade flaw..The both pictures are 2 stamps over each other..Broke them up to see it easier.
ODDITY EIGHTHere is 2 dots appearing inside outer frame line.

There are many, many more..I have just posted a few...Keep your eyes open and maybe you will get lucky and find the next CONSTANT VARIETY..Good luck.
